Strap for Da Vinci Perpetual White Gold / Diamond / White / German

The lug width of the IWC Da Vinci IW8153-09 is 19mm. This measurement represents the distance between the inner shoulders of the lugs and determines strap compatibility. It is essential to verify that your chosen strap has exactly 19mm width to ensure a precise fit and aesthetic coherence with the proportions of the 39mm case.

For the white gold Da Vinci IW8153-09, we recommend natural alligator in anthracite or black, which creates elegant contrast without competing visually with the case. Aged shell cordovan (burgundy or cognac tones) introduces warm chromatic harmony. For daily versatility, medium grey alligator or vegetable-tanned calf leather offers evolving patina that enhances the preciousness of gold.

Strap replacement requires a spring bar tool. Position the small hook under the spring that secures one lug, press gently upward to release the spring, then remove it completely. Repeat on the other side. For the new strap, insert one lug end into the case hole first, then use the tool to compress and insert the corresponding spring. The operation is straightforward but requires care to avoid scratching the white gold case.

Yes, professional-quality aftermarket straps with 19mm lug width are available and compatible. Online you'll find straps in alligator, shell cordovan, calf leather and modern materials such as FKM rubber. For maximum quality and personalisation (length, initials, stitching thread colour), the Casati Milano atelier offers bespoke service with personal material selection and 18-month warranty.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts approximately 5–7 years with daily use, dependent on maintenance and climate. Alligator and shell cordovan age gracefully, developing attractive patina. Aniline leather (undyed) acquires chromatic depth over time. To extend durability, avoid prolonged exposure to direct sunlight and extreme humidity. FKM rubber straps last longer (10+ years) but do not develop patina.
